One reference exhibits a pos- itive temperature coefficient and the other a negative temperature coefficient (Figure 1). The temperature at which the two reference voltages are equal determines the temperature trip point. Pin-selectable +2°C or +10°C hysteresis keeps the output from oscillating when the die temperature approaches the threshold temperature. The MAX6501/MAX6503 have an active- low, open-drain output structure that can only sink cur- rent. The MAX6502/MAX6504 have an active-high, push-pull output structure that can sink or source cur- rent. The internal power-on reset circuit guarantees the output is at TTH = +25°C state at start-up for 50µs. The MAX6501–MAX6504 are available with factory- preset temperature thresholds from -45°C to +115°C in 10°C increments. Table 1 lists the available temperature threshold ranges. The MAX6501/MAX6503 outputs are intended to interface with a microprocessor (µP) reset input (Figure 2). The MAX6502/MAX6504 outputs are intended for applications such as driving a fan control (Figure 3). Hysteresis Input The HYST pin is a CMOS-compatible input that selects hysteresis at either a high level (+10°C for HYST = VCC) or a low level (+2°C for HYST = GND). Hysteresis pre- vents the output from oscillating when the temperature approaches the trip point. The HYST pin should not float. Drive HYST close to ground or VCC. Other input voltages cause increased supply current. The actual amount of hysteresis depends on the part’s pro- grammed trip threshold. (See the Typical Operating Characteristics graphs.) Table 1. Factory-Programmed Threshold Range +35°C < TTH < +115°C +35°C < TTH < +115°C THRESHOLD (TTH) RANGE -45°C < TTH < +15°C -45°C < TTH < +15°C MAX6503 MAX6504 MAX6501 MAX6502 PART |
